"We still don't have any news for you on this topic but I am confident that this is now, once and for all, a 2015 topic," Julius Baer Chief Executive Boris Collardi said, when asked by journalists about the U.S investigation during a conference call after the bank published its full-year results.

Collardi also said the bank did not intend to pass on negative interest rates to clients for the time being, following a move last month by the Swiss National Bank to introduce negative interest rates.
